e7599245cb Add support for --debug-only=interpreter, to print out instrs before 
interpreting them.

Move support for getting the value of a ConstantExpr into
getConstantExprValue(), and add support for the rest of the different
kinds of ConstantExprs.  (I don't think I like ConstantExprs!)
This requires separate procedures executeShlInst() and executeShrInst().

Reduce the number of references to TheEE.

Get rid of an old comment mentioning annotations.

Fix exitCalled(), which was crashing the Interpreter. This was a
leftover from the return-value code refactoring.

when building code with LLVM).

8ddd42c6c1 Upon Chris's suggestion, moved the #ifdef's to the generated C code.

c299416f67 Fixed the CBE on Solaris/Sparc. We need to define the return value of 
the write() system call because it returns 64 bits on Solaris 64 bit,
and an implicit return value of int says it returns 32 bits.
Admittedly, this is a bit of a hack.

895dd78652 Removed the pthread_once() function because it doesn't actually do 
what it's supposed to do.
Just leave this library as a dummy library for now until we have time to
port a real pthread library (or get glibc working).
